Data Engineer | Backend Developer | AI-Driven Automation Specialist
Hello! I’m Johana, a versatile Data Engineer with a background in Electronic Engineering and extensive experience in project management.
My passion lies in turning raw information into scalable, production-grade data products on Google Cloud Platform (GCP). I design serverless architectures, orchestrate complex automations, and apply NLP & AI to extract insights from massive legislative document collections.
- Cloud-Native Pipelines: End-to-end design and deployment of data pipelines on GCP (Cloud Functions, Cloud Run, Workflows, Cloud Storage, Pub/Sub & managed PostgreSQL) handling millions of records daily.
- Automation Orchestration: Orchestrated large-scale scraping, bulk PDF downloads, OCR, and database loading using n8n and Google Workflows.
- OCR & AI Services: Integrated Tesseract (Cloud Run) and OpenAI APIs for text extraction, automatic summarization, embeddings generation, and topic classification.
- Secure Microservices: Built FastAPI microservices containerized with Docker, secured by dynamic ID-tokens (Cloud Run → Cloud Run) to enable credential-free calls from n8n & Workflows.
- Knowledge Graphs: Created semantic graphs of legislative projects, authors, and topics using text-embedding-3-small embeddings and graph visualization libraries.
- Cost & Security Optimization: Implemented fine-grained IAM, VPC connectors, and storage class tuning to cut GCP costs ~40 % while meeting compliance requirements.
- Domain Expertise: Specialized in large-scale processing of government & legislative documents across LATAM.
